Since it was me you originally responded to, let's review the sequence
of events: I was on a pre-filed IFR clearance to Stockton (KSCK), went
missed on the ILS, went back to NorCal and cancelled IFR, requesting
multiple practice approaches. I got the standard "Maintain VFR..." at
that point, then did three practice approaches with NorCal

Oh, well I completely misunderstood your scenario! I thought you were
VFR, not an any IFR flight plan, asked for a "Practice Approach", were
never told "Maintain VFR", and then when you were done with those you
wanted to go home to a previously unannounced airport, were instructed
"report cancelling IFR".
